The study found that workers in high-risk occupations and industry sectors, such as healthcare, appeared to benefit most from access to paid sick leave, the release stated.

According to the release, healthcare practitioners and technicians without access to paid sick leave were 18 percent more likely to suffer a non-fatal work-related injury than those same workers with access to paid sick leave.

"This concept of total worker health, which involves creating an environment of well-being both at home and at work, is an important aspect of the American economy as we depend on able and productive workers," Howard added.

"Many workers may feel pressured to work while they are sick, out of fear of losing their income. If fewer people work while they are sick, this could lead to safer operations and fewer injuries in the work place," said Abay Asfaw, PhD, lead researcher.
